H12-323_V2.0 · Question #551
In WLAN network planning, the final signal field strength is proportional to the AP transmission power and gain, and inversely proportional to the path loss and signal attenuation.
The correct answer is A. True. Option A is correct because the received signal strength at a WLAN client follows the basic link budget equation: Received Power = TX Power + Antenna Gain − Path Loss − Attenuation. Increasing transmission power or antenna gain directly increases the received signal strength…

Explanation
Option A is correct because the received signal strength at a WLAN client follows the basic link budget equation: Received Power = TX Power + Antenna Gain − Path Loss − Attenuation. Increasing transmission power or antenna gain directly increases the received signal strength (proportional relationship), while greater path loss or signal attenuation subtracts from it (inverse relationship). This is a fundamental principle of RF propagation used in every WLAN site survey and capacity planning exercise.
Option B (False) is incorrect because it would deny this well-established relationship - the link budget formula is not controversial; it is the mathematical foundation for all wireless network planning tools and standards.
Memory tip: Think of it as a simple fraction - TX Power × Gain on top (numerator), Path Loss × Attenuation on the bottom (denominator). Bigger numerator = stronger signal; bigger denominator = weaker signal.
